Equine field surgery- Urogenital surgery (Proceedings)

• Left testicles - more likely abdominal
• Right testicles - more likely inguinal
• Previous surgical exploration
– makes identification of surgical landmarks difficult
• If the side of cryptorchidism is unknown, surgery can be prolonged and laparoscopic exploration of the abdomen may be a better approach

• may help determine location
– Horses with abdominal testicles will have a small or indiscernible inguinal ring
– A larger ring with evidence of the ductus deferens entering the canal indicates the horse is an incomplete abdominal cryptorchid, is an inguinal cryptorchid, or has a descended scrotal testicle
• Perform based on temperament and size of the horse, and the anticipated surgical approach
• Bilateral cryptorchidism occurs in up to 15% of cryptorchid horses
